Video: AV1 vs. HEVC: Perceptual Evaluation of Video Encoders

Zhou Wang explains how to compare HEVC & AVC with AV1 and shares his findings. Using various metrics such as VMAF, PSNR and SSIMPlus he explores the affects of resolution on bitrate savings and then turns his gaze to computation complexity.

This talk was given at the Mile High Video conference in Denver CO, 2018.

Video: Best Practices for Advanced Software Encoder Evaluations

Streaming Media East brings together Beamr, Netflix BAMTECH Media and SSIMWAVE to discuss the best ways to evaluate software encoders and we see there is much overlap with hardware encoder evaluation, too.

The panel gets into detail covering:

  • Test Design
  • Choosing source sequences
  • Rate Control Modes
  • Bit Rate or Quality Target Levls
  • Offline (VOD) vs Live (Linear)
  • Discrete vs. Multi-resolution/Bitrate
  • Subjective vs. objective measurements
  • Encoding Efficiency vs Performance
  • Video vs Still frames
  • PSNR Tuning
  • Evaluation at Encode Resolution Vs Display Resolution
